Subject: Re: [PATCH v3 1/2] Support NVIDIA BlueField-3 GPIO controller
Hi Asmaa,
I love your patch! Yet something to improve:
[auto build test ERROR on brgl/gpio/for-next]
[also build test ERROR on linusw-pinctrl/devel linusw-pinctrl/for-next linus/master v6.2-rc7 next-20230210]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
